I don't think being "iconic" has anything to do with anything. I mean, the only thing "iconic" about

before Melee was them starring in an obscure NES game. There was absolutely nothing "iconic" about

or

before they were chosen for their respective games. And what's "iconic" about

and

other than them starring in one of the many sequels of a several years long franchise? What's "iconic" about

? What's "iconic" about

?
Not that I'm saying "non-iconic" third parties have a good chance, but I just don't think the "iconic" thing holds much water.
Also, what's so "iconic" about CommanderVideo that he gets a trophy, other than having games starring him released on many platforms?
...okay, I'm done now.
